The toy body I as illustrated in the Figures 1 and 2 is provided withholes 2 and 3 across which passes the winding shaft 4 having anextension 5 so as to allow the winding up of the spring motor by meansof a key. On the winding shaft are mounted the spring 6, the frictionwheel I and the spur wheel 8, which are all located within the frame 9of the spring motor. The spur wheel 8 engages with the pinion II fixedon the shaft III, while the spur wheel I2 fixed on the same shaft I0engages with the pinion l3 being loosely journaled on the one of therear running axles I4. The pinion I3 is rigidly connected with the U-shaped stirrup member I5 journaled loosely on both therear running axlesI, I6. Each of theaxles I4 and I6 carry at their inner end a crown wheelI! and I8 respectively, with which engages the planet wheel I9 journaledturnably at the stirrup 'nember I5. Thepinion I3, the crown differentialgear by means of which the power of the Spring 6 is transmitted to therear running axles I4, I6. The friction wheell is preferably located inthe longitudinal middle axis of the vehicle I, so that by winding up nocomponent forces can result.

The rear running axles I4, I6 carry the wheels 28. These may consist oftwo discs 2| and 22 which are overlapped at 23. The disc 2| is providedwith projections 24 and 25 and the disc 22 with projections 26 and 21.The object of these projections is to provide supporting surfaces forthe terminal portions of the tire. In addition to this, the projectionsclosely simulate the appearance of the rims of conventional automobilewheels. The outer circumference 28 of the wheels has wedge-shaped form,on which a rubber tire 29 provided with a deep groove 30 of rectangularcross section is put on. By this fact the rubber ring 29 can be formednarrow, because by putting the rubber ring over the wedge 28 the innerend of said rubber ring is expanded, so that the latter shaped with tirecross section at 3I imitates in its appearance the true motor car tire.

The wheels 20 are arranged on axle 'stumps 32 forming the ends of theaxles I4 and I6. The axlestumps carry on their inner side a disc 33having a ring shaped aperture 34, the remaining rim may be provided witha friction lining 35..

The disc has preferably the appearance of the brake drums. The innerendsof the axle stumps carry nuts 36 and the outer ends are providedwith threads 31. The wheels 28 are pushed on the axle stumps and thusclamped by aid of the nuts 38 being screwed on the threads 31, wherebythe wheels rest against the lining 35. The nuts 38 are provided withlateral projections 39 and 40 and constructed at their rear part as nuts4|. The ends of axles I4 and I6 are threaded and are engagingcorresponding inner threads provided in.axle stumps 32. -The rearportion of axle stumps 34 is provided with an integrally formedhexagonal nut 36 which may be engaged with a wrench when it is desiredto put on or to remove wheel caps 38. I

The frame of the driving work 9 isjournaled tumably about the shaft 4passing through the holes 2 and 3. In order to enable the turning therear axles I4 and I6 are arranged within slots 42 and 43 being adaptedin the toy body frame. A spiral spring 45 is positioned with its one endin a hole 44 of the body frame 9 while its other end 46 embraces thesteering spindle 41. Said spiral hole 48 of the toy body and within ahole 49 of a cross rod 58 which is fixed at 5| and 52 at both sides ofthe toy body I. The spring motor frame 9 journaled rockably about theshaft 4 is drawn upwards by the spring 45 whereby the rear running axlesI4, I6 are pressed downwards within the slots '42, 43. 4

In applying a pressure on the toy vehicle in the sense of the arrow 53according to Fig. 1 the rear running axles I4, I6 move upwards in theirslots42, 43 under expansion of the spring 45, so that the friction wheel1 comes in contact with the ground 54. The spring 6 is wound up byrolling thefriction wheel 1 on the ground 54 durv wheel I2 is supportedin a slot 55 at one of its ends. When during the winding operation friction wheel 1 is rotated in a direction opposite to that of the forwardtravel of the vehicle, pinion I I will be rotated and due to thepressure caused by this rotation, its shaft III will be displaced latteris constructed preferably in such a'manner that it does not project overthe circumference of the my body frame I. As to enable a better grip thesteering wheel is checkered at 59.

.The toothed rod 51 is fixed within the holes of the steering lever Mwhich are arranged on brake drum shaped discs 62 carrying the frontwheel stumps 64 provided with a thread 63.

The discs 62 are fixed turnably at the cross rod 50 by means of eyelets65 about a vertical axis. The front wheels 66 are constructed in thesame manner or in another manner as the rear wheels 20 and are fastenedon the axle stumps 64 by aid of the wheel caps 38 screwed on the threads63. The projections 39 and 40 arranged'on the wheel caps 38 serve forthe purpose that the latter can be knocked off from the thread 63 by aidof a hand hammer. The nut 4I serves for the purpose that the caps 38 canbe unscrewed by aid of a wrench. I

Since the steering spindle 41 according to the Figs. 1 and 2 serves ascounter bearing 46 for the spring 45, the steering spindle is held bythe spring tension with friction in its bearings 48, 49. When desired aresilient clamp device I94 can be provided which keeps the steeringspindle .41 so rigidly, that an accidental turning of the sameisimpossible. The clamp device I94 comprises a sheet-like member havingtwo slots I95, I96 provided therein through which the steering spindleis inserted. Slots I95, I96 divide the clamping device or plate I94 intothree parts I91, I98, I99 of which two, I91 and I 98, frictionallyengage one side of steeringspindle 41 and the third, I 99, engages theother side of the steering spindle. The clamp device I94 bears withprojections 200, 20I against corresponding ribs 282, 203 of the toyframe I and is rotationlessly retained therein. Due to the substantialfriction between steering spindle 41 and parts I91, I98 and I99, thespindle is positively retained many of its positions and accidentaldisplacements thereof are prevented. 'It is, also possible, as indicatedin Fig. 39, to give the'steering spindle 41 the necessary friction byarranging advantageously an elastic lining 61 deposited in the bodyframe I or in the cross rod 58. As indicated in the Figs. 35 and 36 thesteering rod 51 is provided with teeth 68 adapted on a segment lyinglevel with the said rod. Since during the steering the rods 50 and and51 change their distance from each other an engagement of the pinion 56with the teeth 68 is secured without any disturbance.

The rack may be-bent in a level lying vertical to it, as shown in Figs.37 and-38, so that in this manner the engagement of rack 51' havingteeth 68 is secured in every position of the steering spindle 41. Thedimensions of the rack 51' are so chosen that the teeth 68 do notproject-above v pinion 8| engaging spur wheel 82 which is fastened-mitted to the driving wheels on shaft 84. Shaft 84 carries the motorspring 83. On shaft 84 is further secured the friction wheel 1, beingcovered on its running surface for increasing the friction with acovering 85 of material. The rear wheels 13 and 14 are arranged on acommon axle 86 supported inthe frame part 69.

a slot 81 and as shown in Fig. '1 in the slots 81, 88 respectively,while the other end is supported rockably in the casing 69 at 89. Thefront part 18 of the frame is jointedly connected with the rear part '69of the frame by aid of a pin 98. These parts 69 and 18 are resilientlyheld in their relative position by the spring 9|, as shown in Fig. 4.

When a pressure is applied on'the toy vehicle from above in thedirection of the arrow 53, the part 18 opposite the part 69 is movedabout the joint 98 against the action of the spring'9l, whereby thefriction wheel 1 comes in contact with the ground 54, as illustrated inFig. 5. Is the toy then moved in direction of the arrow 92 as indicatedon Fig. 4 the spring 83 is wound up by rolling the friction wheel 1 uponthe ground 54 in a direction opposite to that of the normal forwardmovement .of the vehicle. When during the winding operation frictionwheel 1 is rotated, spur wheel 19 will be rotated and due to thepressure caused by this rotation its shaft 88 will be displaceddownwards in slots 81 and 88. Thereby the spur wheel 19 disengages thepinion 18, so that the running wheels 1 I, 12 canturn independently ofthe winding up mechanism of the spring. Under the pressure of the spring83 being wound up the spur wheel 19 is coupled again with the pinion 18,so that the power of the tensed spring is trans- 1|, 12. After thespring 83 is run down the my vehicle runs further by the impartedimpetus. the turning pinion 18 disengages again the spur-wheel 18 on theshaft 88 guided in the slot 81, the winding mechanism of the spring isuncoupled from the front driving wheels 1 I 12. This arrangement allows,as in the casein all shown illustrations of the toy, to draw also such atoy vehicle independently of the spring mechanism by a cord attached tothe eyelet 93, or to draw it without mechanical driving by hand, or pushit by the imparted impetus without disturbance by the driving mechanism.In

this manner it is easily possible to use the toy vehicle for thedemonstration of traffic occurrences, if it is constructed as toy motorcar.

In the form of construction illustrated in Figs. 8 and 9 the springshaft 84 is journaled on its both ends in a slot 94, so that it can bepressed downwards against the action of the spring 91 in the directionof the arrows 95, 96 indicated in Fig. 9. Thereby the toy frame 98 ismade in one piece. By pressing on the ends 99, I88 of the shaft 84 thefriction wheel 1 bears against the ground 54, so that the spring motormechanism is wound up byrolling the toy vehicle in the directionindicated by the arrow I8I in Fig. 8. The

yielding a The shaft 88 is guided with its one end carrying the spurwheel 19- and the pinion 8| in By pushing on I 3 slot 94 has its curvedcentre point in vthe axle supportedin the slot 81, so that the spurwheel 82 engages permanently with the pinion 8|. The uncoupling issecured in -the manner above mentioned by a rocking motion of the shaft88.

In the arrangement shown in Figs. 10 and 11 the shaft 84 is moveddownwards by pressure on a part of the toy body constructed as motor carand thereby the friction wheel 1 brought in contact with the ground 54.The part to be pressed down consists according to the illustrations ofthe steering wheel 58 provided with a stirrup member I82, which isconnected with the shaft 84. When a pressure is applied on the steeringwheel 58 the shaft 84 with the friction wheel 1 is pressed downwardsagainst the action of the spring 91 in the same manner, as illustratedin the Figs. 8 and-9.

In Figs. 12 and 13 a rigid frame 98 is provided in which the axle 86 ofthe running wheels 13,

14 is journaled within a slot I83 arranged in both sides of the frame98.- The axle 86 and the front wheels 13, 14 are pressed downwards by aspring II6 arranged on the frame 98. When pressure is-applied on theframe from above, axle 86 of the running wheels 13, 14 is so far movedupwards within the slot I83, that the friction wheel 1 comes in contactwith the ground 54, whereby the spring motor mechanism can be wound up.In this form of construction it is not necessary to arrange anuncoupling between the friction wheel 1 and the driving wheels 1|, 12,if the slot I83 is so long, that the driving wheels 1|, 12 can be liftedfrom the ground during the toy being depressed.

In Figs. 14 and 15 the running wheels 13, 14 rigidly connectedto shaft86 serve as friction wheels and cause the winding of the spring by thefriction on the ground 54 when the frame 98 is depressed and the toyvehicle is pushed. Shaft 86 carrying a pinion I86 is journaled in slotsI84 and I provided in theframe 98. A spur wheel I81 engages spur wheel82 fixed on the spring shaft. The shaft BB-carrying the pinion I86 ispressed downwards within the slots I84, I85 by the action of the springpinion I86 and the spur wheel I81 are out of engagement. The runningwheel 13 therefor runs light. If pressure is applied on the frame 98 theshaft 86 journaled in the slots I84, I85 slides upwards, overcomes thepower of the spring I88, whereby the pinion I86 engages spur wheel I81.the ground 54 the turning motion of the wheels wheel 82 and thereby tothe spring motor mechanism. The spur wheel 19 uncouples during themotion in the already mentioned manner the shaft 15 from the spur wheel82, so that the toy vehicle can be pushed unobstructed. When the drivingspringis wound up and the frame 98 is released the spring I88 pressesagain. the shaft 86 in the position indicated in Fig. 14 sothat thepinion I86 and the spur wheel I81 are un- I88, so that the 13, 14 istransmitted to the spur coupled. The running axle 86 runs therefor lightand the spring motor being wound up can transmit its power' to the shaft15 over the spur wheel 19 engaging again.

A similar arrangement, as shown in Figs. 14 and 15 is illustrated in theFigs. 16 and 17, in which a three-wheeled vehicle is provided instead ofa four-wheeled toy.

On the shaft as is fixed the single running wheel I89 which causes thewinding up of the spring motor in the same manner as indicated in Figs.14 and 15. Owing to the more compact construction of this device thespur wheel I01 according to Fig. 14 may be omitted.

In Figs. 13 and 19 the friction wheel I is fixed on the shaft 84 whichalso carries the spring 83. On this shaft is further rigidly secured inknown manner an arm H0 which engages with its resilient ends the holesIII of a lock wheel H2 and forms a one-way clutch therewith to preventturning back of shaft 84. The lock wheel engages'pinion I I3 arrangedwith the spur Wheel on a shaft H5. The spur wheel H4 gears with thepinion 16 on the shaft I5 carrying the driving wheels 'I I, I2. Therunning Wheels I3, I4 are pressed against the ground in the same mannerby a spring H6 as indicated in Fig. 12. Is the frame 98 presseddownwards the friction wheel 1 comes in contact with the ground andduring pushing the toy vehicle the spring 83 is wound up.

A further form of construction of the spring motor is illustrated in theFigs. 20 and 21. The frame of the spring motor is journaled in the toybody frame I and consists of the sides I I1 and H8, of the front H9 andthe rear I20. For increasing the stability of the work frame it ispreferred to construct the front side H9 and in some cases the rear sideobliquely whereby a better distribution of the various parts and of theweight in the spring motor is obtained. On the shaft 4 the drivingspring 6, the friction wheel I and the driving spur wheel 8 are mounted.The latter gears with a pinion I2I connected rigidly with the spur wheelI22 engaging with a pinion I23, which is arranged loosely on one or boththe driving axles I24, I25. In addition to this, a differential gear iprovided which consists of the pinion I23 and both the bevel wheels I26,I21, the'planet wheel I28 and the stirrup member I29, in which saidplanet wheel I28'is journaled, while the pinion I23 is fixed to saidstirrup member. It is preferable for this purpose to close the frame I29of the differential gear at I30 in order to create a counter weightagainst the 'frame; part I29 and the planet wheel I 28. The

closing part I30 of the stirrup member is executed accordingly inthickness and fitted with a counter weight or made longer than the framepart I29 weighted with the spur wheel I28 of the differential gear. Thestirrup member I30 can be modified in such a manner, that the legs I3I,I32 of the U-shaped stirrup member I29 are provided with reinforced endpieces. By this weight ba1- 1 ance in the differential gear equalizedrotating masses are created with regard to the axles I24, I25, so thatthe engagement of the driving wheel I22 with the pinion I23 takes placeeasier and quicker. A further advantage is an easier and freer turningof the axles I24 and I25 during running on the ground.

In the Figs, 20 and 21 the pinion I2I and the spur wheel I22are carriedby a lever I33 being turnably arranged about the shaft 4. Said lever I33and the spur wheels I2I and I22 are illustrated'separa-tely in the Figs.22 and 23. Onthe lever I33 projections I34 are, arranged which may bestamped out of the material of the lever I33 as shown in Fig; 23. Theseprojections serve on the one hand for keeping the distance between thelever I 33 and the wheel 8, on the other hand they serve as a kind ofcoupling. between the wheel 8 and the lever I33. In using a frictionwheel for winding up or pushing a spring motor provided with this deviceit is necessary to disengage the pinion I23 and the spur wheel I22 fromeach other, as above described. When the toy is pushed in the directionof the arrow I35 the friction wheel I runs'upon the ground 54, thus thelever I33 is moved in the position shown in Fig. 2|. The spur wheel I22and the pinion I23 are disengaged during this operation. In order toengage the. spur wheel I 22 with the pinion I23 as quickly as possibleduring the running down of the spring in a direction opposite to' thatof the winding the projections I34 are also ofparticular importance.These projections touch the spur wheel 8 lightly, they are engaged anddisplaced upwards owing to the motion of said spur wheel in oppositedirection, whereby the spur wheel I22 is engaged again by pinion I23.The distance from the spur wheel 8 maybe also secured by the sleeve I36,as shown in Fig. 20 by dotted lines.

It has been found to be desirable to limit the rocking motion of thelever I33 which is obtained for instance, by means of a pin I3! locatedin a slot I38 in theside H8 of the frame. This limitation of motion maybe also provided by a simple extension I39 bent over or soldered on theframe respectively,

As shown in Fig. 24 the lever I33 may be provided with a sleeve I40which is secured in the frame part H8 by bending over its terminalportions I4I. This sleeve I40 serves in this form of constructionsimultaneously as bearing for the shaft 4.

It has been found that it is not absolutely necessary-to have therocking point of the lever I33 coincide with the axis of the shaft 4. Asillustrated in the Fig. 25 the lever I33 is journaled rockably in theframe part H8 for example by means of a bolt I42 or in some otherequivalent way.

In Fig. 26 the fastening of the front wheels to the cross rod is shown.This figure clearly illustrates that on the disc 62 constructed similarto a brake drum sleeves I43 are arranged, in the bores I44 of which theextensions I45, I46 can be pressed. Said extensions I45, I46 areattached ,to the cross rod 50 journaled rigidly in the toy body I andserve as bearing pivot for the vertical rocking motion of the wheels. Onthe left side of the Fig. 26 the pivots I45, I46 are shown in elevatedposition and on the right side in lowered position.

A modified form of construction for the fastening of the wheels is shownin Fig. 27, in which pivots I41, I48 are arranged on the disc 62 formedlike brake discs. The cross rod 50 is provided with slots I49,. I50 andwith arms. I5I,' I52, I53, I54 leaving the slots I49 and I50. The armsI53, I54,. I5I', I52 are fitted at their ends with levers I55, I56, I51,I58. By bending up said arms they engage in the bores I 55, I56 of thepivots I41, 14s as shown on theright side of Fig. 27.

In the form of construction for fastening the front wheels depicted inFig. 28, laps I59, I60,

I6I, I62 are stamped out having a bore. The sleeve I43 is arranged onthe disc 62. The fastening of the disc 62 to the toy body I is executedby aid of the pins I63, I 64'being passed through the laps I59, I60 andI6I, I62 respectively and the sleeve I43. In the form of constructionshown in Fig. 28 the front part of the steering rod 41 may be journaledin the toy body I itself.

The Fig. 29 illustrates a modified form of fastening the wheel body onthe axle stumps 54 and 32 respectively, on which is mounted a hub I63having at itsrear end a screw head I64 and at its front end a threadI65. Hub I63 is provided with a flange I66. On said thread I65 isscrewed a cap I68 fitted with a screw head I61 and a flange I69. Betweenthe flanges I66 and I69 the wheel body is clamped, which is fitted inthe same way as shown in Fig. 1.

In Fig. 30 a further modified form of fastening the wheel ontothe axle64, 32 by means of a bayonet joint is shown. Said fastening consists ofa pin I84 fixed on the axle 64, 32 and adapted to engage a slot I86 incap I85, in order to be 'secured thereto by means of arot-ationaldisplacement. Said cap I85 is also provided with a flange I69 as shownin Fig. 29. The wheel body according to Fig. 30 is formed on itscircumference with round surfaces I81, I88 having shoulders I89, I96 anda groove I9I. The rubber tire I92 is put on over the shouldered part ofthe wheel body. Rubber tire I92 is provided with an inside projectionI93 engaging groove I 9I in the wheel body.

Fig. 31 illustrates a particular construction of the hub I93 and of thecap I68, in which the hub I63 is provided with a'cavityflll and the'capI68 also with one "I, so that after screwing together the cavities I10,I form a trough, into which the solid tire I12 is inserted in anysuitable way without being expanded. I

A similar form of construction is shown in Fig.

32. The hub I63 has'an elongated flange I13 fitted with a cylindricalextension. Between the flanges I13, I15 the tire I12 is clamped andadapted to rest on the cylindrical part I14.

The Figs. 33 and 34 illustrate the construction of the friction wheel 1consisting of the two parts I16, I11 and the ring I18 made of a materialwith yielding surface, for instance, rubber. The part I16 carriesprojections I19 engaging corresponding apertures I 80 in part I11. Saidapertures are formed by laps IBI fixed to the part I 11. The

laps I8I are provided with projections I82 passing through holes I83 ofthe part I16 and being bent over after connecting the parts I16, I'I'Lasshown in Fig. 33. The friction surface I 18 is either pushed on one ofthe parts I16 or I11 before con- 3 necting or inserted into the grooveformed by ,the parts I16, I11 and the projections I19, I8I

after bending over.

In the bottom of the toy body an opening 204 is provided through whichthe difierential gear becomes visible from the underside. Through afurther opening 205 the friction wheel 1 projects.
